This invention relates to new and useful of lano confi uration as clearldisclosed in a j Y spindle 7.

improvements in tire removing devices and aims to provide a novelrelatively simple and efficient device whereby tires may be quicklyforced from the solidnon-collapsible types of rims and this in a rapidmanner and without bending the rims of without damaging the tires.

In carrying out the present invention there is provided means forholding atire carrying rim, and thisregardless of the size thereof,other means being provided for engagement with the tire and soconstructed as to force the tire from the rim during the operation ofthe machine, said tire engaging means being also adjustable so as tofacilitate the removal of tires from rims of varying sizes.

An important objectof the present invention is to provide a machine ofthis character that is readily adjustable to tires and rims of varyingsizes and one that may be operated by a single person and this withoutrequiring great effort. 1

With the foregoing and other objects in view as the nature of theinvention will be better understood, the same comprises the novel form,combination and arrangement of parts hereinafter more fully described,shown in the accompanying drawing claimed. t i i In the drawing whereinlike reference characters indicate corresponding parts throughout theseveral views:

Figure 1 is a perspective of my improved machine. g t

Figure 2 is a fragmentary perspective of one of the rim supporting'dogs,the'rim being fragmentarily disclosed in perspective and cross section,and

Figure 3 is a fragmentary section disclosing one of the dog units perse.

Now having particular reference to the drawing, my novel machineconsists of a base 5 from the center of which rises a standard 6preferably of four sided construction and to the upper end of which isrigidly attached a vertically projecting non-rotating worm Securelybolted to the four sides of the standard 6 are dog brackets 8, each ofwhich is formed at its outer side with outwardly projecting spaced ears99 extending across the lower edges of which is a con necting web 10:Pivoted between these ears 9- above web 10 as at 11 is a plate dog 12the upper edge of each of which is the three views.

These dogs are adapted to support a solid non-collapsible rim of thetype fragmentarily disclosed in Figure 2 and designated by the referencecharacter A. Rims of this character are usually formed upon their innersurfaces with a circumferential shoulder B beneath which the upper endsof the dogs 12 are arranged so as to support the rim upon which is the.usual tire, not dis closed, in horizontal position aroundthe basestandard 6. The upper edge of each dog 12 v is formed with a notch 13 soas to permit of the support of the smaller designs of solidnon-collapsible rims.

rotatable collar 14 formed at its surface with fourequally spacedsockets 15withinwhich are rigidly mounted the inner ends of circularbars 16, also four in number. Associated with each bar'16 is adownwardly and diagonally extending elongated U-shaped bumper bar 17,the right angular ends of which are engaged within openings in the bars16 and secured thereto by nuts 18 threaded upon the ends thereof. Thehorizontal portions of these bumper bars are in spaced parallel relationwith the'bars 1 6 as clearly disclosed in Figure 1. I

Freely slidable upon each bar 16 within the ends of its respectivebumper 17 is acollar 19 formed with :1 depending short arm 20 thatengages against its'respective bumper 17. The lower end of each arm isconstructed for receiving-a roller 21, while the surface of the arm inengagement with its bumper is formed with teeth 22 for enga 'ng teeth 23at the arm contacting surface 0 the bumper for preventing the movementof the arm carrying collar upon its particular bar 16 after the collarhas been properly adjusted and the arm swung into engagement with thebum er. s

As disclose in Figure 1, two opposed arms 16 are of greaterlength thanthe other two arms so as to provide turning handles for the collar 14that is threaded upon the worm '7. Obviously, after a tire carrying rimhas been properly supported upon the dogs 12 and the roller carryingcollars 19 have been adjusted upon their particular bars so as to engagethe tire upon the rim, the elongated bars 16 are then grasped and turnedso that the collar 1 1 is threaded downwardly upon the Threaded upon theworm spindle 7 is a.

Worm 7 which will of course cause the removal of the tire from the rimby reason of the engagement of the rollers Ll thereagainst.

It will thus be seen that I have provided a highly novel, simple. andeiiiciently operat' ing tire removing machine that well adapted for allthe purposes heretofore designated and even though I have herein shownand described the invention as ronsisting oil certain detail structuralelements it is nevertheless to be understood that some changes may bemade therein witl'iout alt "11g the spirit and scope of the appendedciaims.

Having thus described the invention, What I claim isz- 1. In a tireremoving machine oil the character described, a rigid standard, aplurality of dogs arranged in spaced relation around the standard forsupporting a tire tt'L1'l' /l1]g rim, a stationary worm bar extending;from the standard, a collar threaded upon the bar, a plurality of barsrigidly associated with the collar and projecting radiall therelfroni,arms slidably associated with the bars and depending therefrom forengaging the tire arranged upon the rim and means for limiting theswinging of the arms in a certain direction during the turning oi. thecollar to force the tire from the rim by the engage meat of the armstherewith.

2. In a tire removing machine of the character described, a standzufd,means surround ing the standard for SllPPOltlllg a tire carry ing rim,said means being adjustable for supporting rims of various sizes, aWOLIH bar projecting from the standard. a collar threaded upon the bar,a plurality of radially extending bars associated with the collar, armsslidablo upon the bars, means in the lower ends of the arms for engagingthe tire upon the rim to cause the forcingot' the tire from the rim whensaid collar is turned downwardly and means for limiting the inwardswinging movement of the arms while in engagement with the tire andwhile said collar is rotated in a tire engaging direction.

3. In a tire removing machine of the charactor described, a standard,means surrounding the standard for supporting a tire carry ing rim, andincluding adjustable means for acconunodating rims oi' varimis sizes, aWorm bar projecting from the standard, a collar threaded upon the bar, aplurality of radially extei'iding bars associated with the collar, armsslidable upon the liars, means in the lower ends ol the arms forengaging the tire upon the rim to cause the forcing of lhe tire from therim when said collar turned downwardly and means for limiting the inwardswinging n'ioremcnt of the arms while in engagen'ient with the tire andwhile said collar is rotated in a tire engaging direction, and meansbetween said arms and said, means for maintaining the arms atpredetcrmined position upon the bars.

i. In a tire remorii're machine ot the character described a standard,means surroumiling the stamlard :ior supporting a tire carry .ing rim,said means being adjustable for suppintii'ig stems of various sizes, aworm har projecting From the standard, a collar threiuil' ed upon thebar, a plurality of radially extending bars associated with the collar,arms sl'idahle upon the bars, means in the lower ends of the arms forengaging the tire upon the rim to cause the forcing of the tire from therim when said collar is turned down- Wardly and means for limiting" theinward swinging movement of the arms while in em gagcment with the tireand While said collar is rotated in a tire engaging direction, meansbetween said arms and said means tor unlintaining the arms atpredetermined position upon the bars, said first mcnliomed meamconsisting of bumper bars arranomil la-neath the collar carrying bars inspaced parallel relation therewith and said second menthmml meansconsisting of ribs upon the brunper bars, and coo 'ierating ribs uponthe adjacent sides of said arms.

In testimony whereof I atlix my signature.
